lol))... what's the point? Half of them are from Heroes of Might and Magic III)) It would be better to take them all from there. IMHO... because a mage/wizard doesn't really fit... where are the warriors?)... You yourself wrote that you need MAGES and WARRIORS)

Elves - Ranger and Druid... Archdruid doesn't really fit...
Necromancer and Dark Knight... no vampires, then take Undead instead...
Stalker is a level 1 unit)) It's better to come up with another name...
The rest are fine...
